As the memory storage capacity of the SSDs increases, more immediate backup energy is also needed accordingly, so a larger number of Tantalum Capacitors (TC) must be mounted on SSDs. On the other hand, as SSDs becomes thinner and more compact, limitations on surface mounting area and height of electric components are also tightened.

Kyocera AVX Low ESR Tantalum Capacitors Technical Paper
Tantalum capacitors are particularly well suited as energy storage elements in ripple filter circuits due to their low ESR. Since AC ripple is continuous and periodic, the capacitor ESR results in a continuous generation of heat as the current flows in and out of the capacitor. This is especially true in high-frequency switching supplies and ...
